Research on the Influence of Epoxy Resin from Hydrothermal Aging

Article Preview

Abstract:

Through the experiment on hydrothermal aging, the influence on the properties of epoxy resin is studied, while monofilament tensile test and the corresponding structural analysis are carried out on the test samples. The result shows that the hydroscopicity of resin conforms to Fick 2nd law; the balance amount of hydroscopicity is 5.15%; the spreading coefficient of moisture in compound material is 1.6538×10-6mm2/s; the descending trend of the mechanics of resin corresponds with the increasing trend of hydroscopicity; the mechanism of hydrothermal aging of resin is the spreading of water molecules and the hydrothermal influence on materials, without any obvious post-solidity and physical aging.
